Abstract
Culture of domestic cat preantral follicles can be a suitable technology to assist oocyte conservation strategies in the family Felidae. This research was aimed to comparatively analyse cat preantral follicular development of follicles directly seeded on growth surface or encapsulated in 0.5 or 1% of sodium alginate in a serum-free medium containing FSH, EGF and IGF-I. Preantral follicles were isolated from cat ovarian cortical tissue after ovariectomy. Alginate was dissolved at 0.5 or 1% in PBS. Follicles, 4 per well, with 0% (G-0%), 0.5% (G-0.5%) or 1% (G-1%) of sodium alginate were cultured in M199 with FSH (100 ng/mL), EGF (100 ng/mL) and IGF-I (100 ng/mL) for 7 days at 37°C, 5% CO2 and 99% humidity. Culture medium was replaced every 48 h and samples were stored at -20°C until ELISA of steroid hormones. Morphometric evaluation of follicles was performed every 24 h. G-0% follicles showed granulosa cell migration away from the oocyte and disrupted morphology, whereby they reached apparently larger diameters (203.70 ± 5.82 μm; p < .05) than G-0.5% and G-1% follicles (157.89 ± 8.47 μm and 95.23 ± 1.67 μm, respectively) which maintained three-dimensional organization, being larger in G-0.5% than in G-1% (p < .05). G-0.5% follicles attained the multi-layer preantral follicle stage on day 7 of culture, whereas G-1% follicles underwent progressive atresia. On day 6, steroid concentrations were higher (p < .05) in G-0% than in G-1%: 60 ± 19 vs 0.88 ± 0.32 pg/mL oestradiol; 2.6 ± 0.84 vs 0.04 ± 0.02 ng/mL progesterone; 1.3 ± 0.22 vs 0.61 ± 0.04 ng/mL testosterone and 1.6 ± 0.54 vs 0.22 ± 0.07 ng/mL androstenedione respectively. Steroid concentrations in G-0.5% were comprised between those of G-0% and G-1% (p > .05). In conclusion, two-layer cat preantral follicles encapsulated in 0.5% alginate cultured in medium containing FSH, EGF and IGF-I can develop up to the multi-layer preantral stage in 7 days of culture, whereas follicles directly seeded on growth surface or encapsulated in 1% alginate lost their three-dimensional organization, and experienced regression with compromised steroidogenesis, respectively.

Abstract
PURPOSE The objective of this work was to analyze the long-term prevalence of urinary and fecal incontinence and their impact on quality of life in patients with advanced and recurrent ovarian cancer treated with cytoreductive surgery and hyperthermic intraoperative intraperitoneal chemotherapy (CRS + HIPEC). METHODS This cross-sectional study included a series of patients with advanced and recurrent ovarian cancer treated by CRS + HIPEC, with a disease-free period of at least 12 months after the procedure. Urinary incontinence was evaluated using the International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF), fecal incontinence using the Wexner test and the Fecal Incontinence Quality of Life (FIQL) questionnaire and global quality of life using the Short Form 36 (SF-36) survey. RESULTS A total of 64 patients were included in the study, with a median age of 55 years (range 28-78). The urinary incontinence rate was 45% and the fecal incontinence rate was 20%. Up to 14% of the patients presented both types of incontinence. The presence of urinary or fecal incontinence generated a significant negative impact on quality of life in relation to patients without incontinence. DISCUSSION Urinary and fecal incontinence is frequent in the follow-up of ovarian cancer patients treated with CRS + HIPEC. Reconsidering the approach to the pelvis without peritoneal metastases in the peritoneum could modify the incidence of these pelvic floor dysfunctions.

Abstract
Isoflavones, such as genistein, have been proposed to have beneficial effects on health, including preventive or therapeutic actions in carcinogenesis. Their structural similarity to oestrogens allows them to bind at the cellular level with oestrogen receptors. Therefore, this study attempted to determine the antitumoural effects of genistein administered in a canine inflammatory mammary cancer xenograft model, in terms of tumour proliferation, appearance of metastases and steroid hormone regulation. Using histology and immunohistochemical analyses as well as the EIA technique for hormonal determinations, the antitumoural effects of genistein on an inflammatory mammary cancer xenograft model were assessed for 3 weeks. Mice treated with genistein showed higher Ki-67 levels than the control group. There were significantly more distant metastases in the genistein-treated xenografts versus the control group. Intratumoural and serum progesterone, androstenedione and oestrogen levels in treated mice were elevated, whereas intratumoural testosterone levels were decreased compared to the control group. These results revealed that genistein ingestion promotes tumour proliferation and elevates metastatic rates by increasing intratumoural and circulating oestrogen levels in a mammary cancer xenograft model.

Abstract
The involvement of epidermal growth factor receptor (EGFR) is well established in human breast cancer, however, in canine mammary tumours (CMT), including inflammatory mammary carcinomas (IMC), still needs to be clarified. Enzyme immune assay techniques were used for EGFR determinations in tumour tissue from 45 bitches with CMT and in normal mammary glands from eight control dogs. Higher tissue EGFR levels were found in CMT compared with controls (P < 0.05). In malignant CMT, tissue EGFR elevated concentrations were statistically significantly associated with tumour relapse and/or distant metastasis during follow-up and with reduced disease-free and overall survival times. The IMC cases had the highest tissue EGFR levels compared with other malignant non-IMC tumours (P < 0.001). The results support the hypothesis that EGFR levels influence prognosis in malignant CMT, suggesting that EGFR may represent a therapeutic target in cases of high histological aggressiveness and especially in cases of metastatic phenotype and poor prognosis.

Abstract
Hormonal dependency of canine mammary tumours (CMT) has been studied over the last few decades. However, studies assessing the prognostic and predictive potential of serum and/or tissue steroid hormone levels are still scarce in CMT. To the best of our knowledge, this is the first report relating serum and tissue levels of steroid hormones and prognosis in dogs. Serum and tumour tissue from 45 female dogs with spontaneous CMT were included in the study. Moreover, serum and normal mammary tissue from 13 healthy female dogs were also included as controls. Steroid hormones were determined by competitive enzyme immunoassay. Overall, levels of steroid hormones in serum and tissue homogenates were significantly different between malignant and benign mammary tumours (p < 0.01), except for progesterone (P4) serum levels that revealed no statistical differences between groups. In malignant tumours, oestrone sulphate (SO4E1), dehydroepiandrosterone (DHEA), androstenedione (A4), testosterone (T) and P4 elevated tissue concentrations were significantly associated with tumour relapse and/or distant metastasis during follow-up. A significant association was found between elevated tissue SO4E1 (p = 0.003), 17β-oestradiol (E2) (p = 0.036), DHEA (p = 0.022), A4 (p = 0.001) and P4 (p = 0.013) concentrations and shorter disease-free survival and overall survival in female dogs with malignant mammary tumours. The high levels of tissue steroids found in cases of poor prognosis open the possibility of additional new therapeutic approaches. Future clinical trials will be needed to clarify the usefulness of targeting steroid hormones in the treatment of this neoplastic disease.

Abstract
BACKGROUND We analyzed the role of hyperthermic intraoperative intraperitoneal chemotherapy (HIPEC) on the microscopic component of the disease in patients with a first recurrence of platinum-sensitive ovarian cancer after complete cytoreduction (CCR). PATIENTS AND METHODS We analyzed the data of 54 patients who were operated on between January 2001 and July 2012 with the diagnosis of platinum-sensitive recurrent ovarian cancer. In all patients, it was possible to achieve a CCR. Patients were divided into two groups: group I (cytoreduction alone) consisted of 22 surgical patients and group II (cytoreduction and HIPEC) consisted of 32 patients. RESULTS There were no significant differences in any of the preoperative variables studied. After a multivariate analysis of factors identified in the univariate analysis, only the presence of tumors with undifferentiated histology (hazard ratio 2.57; 95% CI 1.21-5.46; p < 0.05) was an independent factor associated with a reduced disease-free survival. The 1- and 3-year disease-free survival was 77 and 23% in patients from group I and 77 and 45% in patients from group II, respectively, with a tendency, but no significant differences (p = 0.078). There was no significant difference in postoperative morbidity between the two groups. CONCLUSIONS The administration of HIPEC in patients in whom it is possible to achieve a CCR of the disease has not increased postoperative morbidity and mortality rates in our center. HIPEC with paclitaxel is effective in the treatment of microscopic disease in platinum-sensitive recurrent epithelial ovarian cancer patients with microscopic residual disease after cytoreduction, although with no statistically significant difference.

Abstract
BACKGROUND We analyze the efficacy of hyperthermic intraoperative intraperitoneal chemotherapy (HIPEC) for microscopic residual disease in patients with stage IIIC/IV ovarian cancer after a complete cytoreduction of their disease. PATIENTS AND METHODS We analyzed the data of 87 consecutive patients diagnosed with stage IIIC/IV ovarian cancer operated between December 1998 and July 2011. In every patient it was possible to achieve a complete cytoreduction of their disease. (Since January 2008, our center has incorporated the use of HIPEC in patients with peritoneal surface malignancies, including patients with peritoneal dissemination of primary ovarian cancer.) RESULTS Of 87 patients, 52 were treated with HIPEC (paclitaxel 60 mg/m(2), 60 min, 42 °C). After a univariate analysis, factors associated with lower disease-free interval were: performing a gastrointestinal anastomosis, operative time greater than 270 min, poorly differentiated histology, and not being treated with HIPEC. After multivariate analysis, independent prognostic factors included not being treated with HIPEC [hazard ratio (HR) 8.77, 95 % CI 2.76-14.42, p < 0.01] and the presence of poorly differentiated tumors (HR 1.98, 95 % CI 1.45-8.56, p < 0.05). Disease-free survival at 1 and 3 years was 66 and 18 %, respectively, in patients without HIPEC and 81 and 63 %, respectively, in patients treated with HIPEC (p < 0.01). HIPEC administration did not alter the results obtained for disease-free survival in patients with undifferentiated tumors. CONCLUSIONS The treatment of the microscopic disease following complete cytoreduction with HIPEC in patients with advanced ovarian cancer is effective and can prolong disease-free survival. This survival benefit was not seen in undifferentiated tumors.
